From the outset, the vision of the Regional Earthquake Likelihood Models (RELM) project recognized that the best way to come to grips with the full impact and uncertainty in earthquake hazard estimates is to compare a wide range of independent, well-documented, and physically defensible hazard models that produce identically formatted output. Ideally, these models should be rooted in the complete spectrum of geophysical input. Toward this end, I offer testable earthquake potential maps based on geodesy, geology, historical seismicity, and computer simulations of earthquakes.

Motivation. Until recently, earthquake rate estimation was entirely the domain of geologists and seismologists. With well-defined...
